T0 all whom fit may concern Be it known that we, CLAES F. Romano andAUGUST A. MALMBERG, citizens of the United States, and residents of thecity of Chicago, county of Cook, and'State of Illinois, have inventedcertain new and useful Improvements in Mangles, of which the followingis a specification.

. Our invention relates to laundryfmangles, or vpressing devices, andhas for its object the production of.a machine of this character whichwill be of durable and economical construction, and efficient inoperation.

Laundry mangles of the present construction are comprised of a centralheated roller and a plurality of padded rollers which, when the machineis in operation, rotate in contact with said heated roller, the articleto be pressed being passed between said rollers By reason of the heatedcondition of the heated roller in the event of cessation of operation ofthe machine, if the padded rollers are permitted to remain in engagementwith the heated roller, the padding upon the former is burned orotherwise inj ured to such an extent as to necessitate removal thereofand the provision of new padding. This being so it is essential in 'theoperation of a mangle of the class mentioned, to provide means foreecting ready outward movement of the padded rollers from engagementwith the heated roller, the instant that operation of the machineceases.

It,is the object of the present invention to provide such means and sothat in the operation of a mangle the padded rollers may be readily andexpeditiously moved from contact with the heated roller with the use ofminimum exertion on the part of the operator of the machine.

Other objects will appear hereinafter.

'lheinvention consists in the combina tions and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Figure 1 is a front elevation of the upper end portion of a mangleembodying` our invention, ythe central portion thereof being brokenaway, Figf2 is an end elevation of Fig. 1, Fig. 3 is a verticaltransverse section taken on substantially line Ym--fv of Fig. 1,'Figi-lf is an enlarged sectional detail illustrating fthe mounting ofthe respective ends of the heated roller of the device, and Fig. 5 is asectional detail shoWinO the mounting of the respective ends o? thepadded or movable rollers embodied in the device.

The preferred form of construction as illustrated in the drawingscomprises spaced supporting frame members 1, the lower ends of which notshown) bein of any Suitable form for fastening to the oor. Arrangedbetween the upper ends of the supporting rframe members ,1 is a heatedroller 2 the `journals fl of which are mounted in stationary bearings 4Yprovided in the frame members 1, as clearly shown in Fig. Il. One of thejournals 3 is provided with a gear 5 which meshes with a pinion 6provided upon a stud sha ft 7. Also carried by the stud shaft 7 is aworm wheel 8 which meshes with a worm 9 fixed to a shaft 10, the latterbeing provided with the drive pulley 11 which is adapted for connectionwith a belt or other suitable means of power transmission Aferconnecting the device with a motor or other means of driving employed.

Arranged around the heated roller 2 is a. plurality of padded rollers 12the journals 13 of which are mounted in bearing blocks 14 which areslidably mounted in slots 15 formed in the frame members 1 disposedradially relative to the axis of roller 2. The rollers 1Q are normallyheld at their inner terminals of movement in contact with the heatedroller 2 through the medium of helical compression springs 16 the innerends of which contact with the bear` ing blocks 14 as clearly shown inFig. 5. The outer ends of said springs are arranged in housings 17 whichare provided at the outer ends of slots 15, said housings evidentlyserving to maintainy the springs in operative position. Threaded in theouter ends of housing 17 are hand screws 1S the inner ends of whichcontact with the adjacent ends of said springs 16, the arrange` mentbeing such that the tension of said springs may be varied or adjusted bysimply manipulating said screws 18 as will be readily understood.

`Provided at corresponding ends ofthe journalsl are pinions 19 whichmesh ,with the gear 5, the arrangement beingsuch. that` in the operationof driving pulley 11 and hence the heated roller 2, the padded rollersthat when said padded rollers are moved mitwardly by reason of theoutward sliding of the hearings lyi thereof in slots lo, said lceth willmove ont of mesh and permit of free rotation of said padded rollers.This ol special advantage in that the wrapping of ihe padding stripsaround said rollerf-f or thev un wrapping of said strips thereof may bemore readily effected when said rollers are free so that the same may berotated h v the hand in the wrapping or unwrapping thereof. iWithoutthis arrangement in the wrapping or unwrapping of the padded rollers, itwould be required to rotate the entire mechanism with which said rollersare operatively connected during operation of the mangle.

Arranged within the heated roller is the usual tubular fuel burner 20which` when the device is in use. is connected with any suitable sourceof fuel supply, the llames or yiets which are supported by the fuelissuing from said burner serving to heat the roller 2. iirranged at oneside ot' said roller is a table 2l which Vis supported upon arms 22projecting from the frame members 1. 'In thc operation of the mangle thearticles to he prt d or ironed are fed from the table '2l 'to a positionbetween the padded and heated rollers, the article in the course ot itspressing passing partially around the heated roller successively' intoengagement with the padded or movable rollers. The gears lil are soproportioned relative to each other that in the operation of themachine. the second of said rollers will be rotated slight-lv fasterthan the first and the third slightly faster than the second, the firstgea r being preferably provided with twenty teeth. the second gearwithnineteen teeth and the third with eighteen teeth. Through thisarrangement. the article. as the sanle passes through the inangle. willbe stretched in the passage thereof from one of the padded rollers tothe next which will serve to remove any transverse wrinkles and thusconduce to perfection in the work turned ont.

("oiiperating with the bearing blocks i4 of cach of thi` padded rollersare toggles 23. the ou ends of said toggles being pivotcomici-imi at 2iwith said bearing the under sides of said bearing being VLM-Werd asclearly shown in and fr for lureccg'ition of lsaid ends `iid ioge'hs.The opposite ends of said ;--t are piotallv connected at 2.7 with -l`r:ri.'A nrcnh .said pivotal points be- .u :itin/nant with the center lincsof l lo-!-;--. livin-2' positioned in planes` -iu Liironatim avcof thixheated and lv rolle: as clearly shown in Fig. 3. ioiiils, o. llntogglcsai. correspond` fil' ily mangio are conncctcil by .was :o will.; acircular actuating mcn'iher 27 which is rotatably mounted upon anextension of the bearing 4 at the corresponding end of the machine, saidactuating member being provided with arms 28 for connection with saidlinks, as shown. The arrangement is such that, upon clockwiseoscillation of the members 27, the toggles 23 will be simultaneouslyactuated to cause outward movement of the padded rollers, When thepadded rollers are at their eater terminals of movement the toggles 23will be in straightened position or at 'dead eenters. thereby etlcctingthe locking of said toggles and hence said rollers in this position,inward or return movement of said rollers being permitted only uponbreaking ot said knee joints by reverse movement of the actuatingmembers 27.

Depending from the actuating members 27 are arms 29 with which engagelinks 30 connected at their forward ends with rocker arms 31 dependingfrom a rock Shaft 32 the extremities of which are mounted in fraaiemembers 1. Thus the actuating members 27 at the opposite ends of thedevice are connected for simultaneous movement and so that when the rockshaft 32 is operated both cnds ofthe padded rollers will becorrespondingly moved. Provided at oml end ot' the shaft 32 is anupwardly Aprojor-ting handle or lever 33 whereby said shaft may bemanually rocked to effect the desired movement of the padded rollers ofthe device.

With this arrangement it will be seen that in the operation of themangle in the event of the rollers ceasing operation, the padded rollersmay be readily and expeditiously moved out of engagement with the heatedroller by simply rocking the lever 33. Through the use of toggles greatleverage results and therefore rocking of the lever 33 to effect outvard moveinent of the padded rollers may be eflected with little exertionapplied to said lever.

A mangle ot' the construction set forth is durable and economical inconstruction, the same may be readily and easily operated and is of highefficiency.

lVhilc we have illustrated and described the preferred forms ofconstruction for cariving our invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. lVe, therefore, do not wish to bo liniiied lo (he precisedetails of construction set forth, but desire to avail ourselves of4auch variations and modifications as come within thc scope of theappended claims.
